SPECIFICATION forming part of Letters Patent 170,308,2-1-2, dated I Tvember 18, 188%.

Application filed January H, 1884. (No model.)

T 0 all whom it may concern:

Be it known that I, PAUL EnRLron, residing at Gohlis, near Leipsic, in the Kingdom of Saxony, German Empire, have invented a new Mechanical Musical Instrument, of which the following is a specification.

My invention relates to musical instruments in which reeds or pipes or other devices suitable for bringing forth musical notes are caused to sound by mechanical means so as to produce a melody; and its object is to so construct the instrument that it will act, by being bodily swung around 011 a non-rotating axle, more effectually than has been attained by the devices heretofore employed. For this purpose the parts operating to produce the notes are inclosed in or attached to a box or frame arranged to be rotated upon an axle passing through the instrument at a certain distance from the center of gravity thereof, and one end of which is adapted to be held in the hand, a worm and wheel and a crank being pro' vided by which the operating parts are actuated when they are caused to rotate around the axle.

On the annexed two sheets of drawings, Figure 1 shows in sectional elevation, and Fig. 2 in sectional plan, a mechanical musical instrument with my invention applied thereto. Fig. 2 is a plan view of the perforated band F, Fig.1. Figs. 3 and 4 are respect ively a sectional elevation and transverse sect-ional view of another instrument comprising my invention. Figs. 5 and 6 are details there of. Fig. 7 shows in sectional elevation, and Fig. 8 in transverse section, an instrument of the hind described in the specification of my United States Letters Patent No. 290,672, and also involving my present invention. Fig. 9

is a part in detail.

In all these instruments the box 0, in which the operating parts are inclosed or to which they are attached, is rotativel y connected to an axle, A, having at one end a handle, A. By

4 5 this handle the instrument is held in the hand while it is swung around on its axle. On the said axle there is a screw thread or worm, B,

engaging with a worm-wheel, (I, from which motion is conveyed to certain valve-operating devices, and to the end of the axle is iixed acrank, K, on which turns one end of the connecting-rod L, whose other end acts on the bellows I. It will be seen that by these means the wheel 0 is rotated and the connecting-rod operated when the instruu'ient is handled as described.

The other portions of the instruments rep resented by drawings do not in themselves constitute any part of the invention but I shall briefly describe them in order to c0n1- 6o pletely show how the invention may be applied in practice.

According to Figs. 1, 2, and 2 there is fixed upon the axle of the aforesaid wheel C a roller,

1), over which and the auxiliary rollers E and E runs a continuous traveling band, F, having perforations corresponding with the notes to be produced, and adapted to register with the beaks of levers a, connected to the valves of reeds 71, provided withvibrating tongues 1 the parts being so arranged that when a per foration is opposite to the beak of a lover, a, this lever and the valve attached to it will be lifted by a spring, I), and the corresponding note will be sounded by the air fed into the chamber H by the bellows I, and the press ure whereof is regulated by the bellows M.

G is a tension-roller for the band F. If pre ferred, the said band may also be operated by the wheel 0 when it is coiled on an axle, M, So and attached with one end to the roller I).

In the instrument shown bylligs. 23 to (3 the axle of the wheel 0 carries a cylinder, D, adapted to actuate the valve-levers a. by means of pins and cams iixed on its surface, or in S5 grooves turnedinto the surface. The cylindermay,however, also be constructed with notches in which engage the beaks of valvedevers constructed as iirFig. 1; or the cylinder is made hollow and provided with perforations 9o for the same purpose.

In order to allow various tunes to be played on one instrun1ent,the cylinder I) may he made with an exchangeable sleeve carrying the pins, notches, or perforations; or the said pins, notches, or perforations are attached to or formed in flat sheets of any suitable material means than those shown in the drawings, and adapted to be fastened on the surface of a I described.

smooth cylinder. Moreover, sheets of this kind may be caused to run over two or more cylinders or rollers, in a similar manner as in the instrument shown by Figs. 1 and 2, the beaks of the valve-levers being in this case opposite to one of these cylinders or rollers.

According to Figs. 7 to 9 the axle of the worm-wheel O has a perforated disk, D", attached thereto for operating the valve-levers a, the said disk rotating between two rows of tines, 6, Figs. 8 and 9, by which, besides, the levers a are guided. The outer row of these tines is fixed to a bar, f, that may be turned up for allowing the diskto be exchanged. The bellows I are actuated in the latter two instru ments in the same manner as in the one de scribed first.

The invention, may, however, also be applied to instruments in whichthe notes are produced in other manner, or in which motion is conveyed to the operating parts by other I claim as my invention In a mechanical musical instrument pivoted on an axle, A, not passing through its center of gravity, and having a handle, A, adapted to hold the instrument by, the combination, with the said axle, of a worm, B, engaging with the worm-wheel C, from which motion is conveyed to the reed-operating devices, and of a crank, K, connected by the rod Lto the bellows I, the said worm-wheel O and rod L being actuated when the instrument is swung round on its axle, substantially as and for the purpose specified.

In testimony whereofl have signed my name to this specification in the presence of two subscribing witnesses.
